1 taint. i214) This invention is a scissors or shears sharpener tool or implement of simple construction, that may be kept in a housewifes sewing or work basket or hung upon a nail or hook, which is instantly available for use, and which has no parts to get out of repair or that presents a cutting edge from which a careless person may receive a cut or injury, and yet which is exceedingly effective for the purpose intended.

In order that the principle of the invention may be readily understood, 1 have disclosed a single embodiment thereof in the accompanying drawing, wherein:

Fig. l is a front view of the scissors sharpener, tool or implement;

Fig. 2 is a back view thereof;

Fig. 3 is a transverse cross section taken on the line 33 of Fig. 2;

Fig. 4 is a side view, partly in section, showing a pair of scissors being sharpened; and

Fig. 5 is an edge view of the upper portion of the scissors sharpener, with a pair of scissors positioned therein.

The scissors or shears sharpener constituting my invention operates upon the principle of presenting a sharpening element which is preferably an emery stone, or hone, having the form of a rounded bar and fixed at just the proper angle of inclination in a holder or support in the side Walls of an opening in the holder, the side walls above and below the sharpener element being at a proper angle of inclination to constitute guides against which the two blades of the scissors or shears are firmly held while drawing the scissors or shears repeatedly back and forth through the said opening in firm contact with the sharpener element, and thereby removing burrs or the like and also actually sharpening the scissors or shears.

Referring more particularly to the drawing, the body of the holder or support is indicated at 1, and it is preferably provided with a handle 2 that may be conveniently grasped in one hand, preferably the left hand of a righthanded person, during the sharpening process, and so that the scissors or shears may be grasped in the right hand and subjected to the sharpening process.

While the holder or support may be formed of any suitable material, I preferably form it of plastic material known as T enite, in a mold that may be a small capacity mold or in one having a number of mold cavities.

While my invention is not limited to any proportions or size or dimensions of parts, I may and preferably do make the holder or support six inches in length and two inches in width. The drawing, as filed, shows the tool or instrument of full size, or substantially so. While it may be of any suitable thickness and may be of uniform thickness throughout, I herein form the holder or support with a beaded rim 3, extending entirely about the same at the back, the front being smooth. The handle 2 may be about two and three-quarter inches long, and the thickness of the holder or support 1 inside the rim 3 may be about two thirds the thickness of the rim 3,

2,713,238 Patented July 19, 1955 excepting the part that immediately surrounds the lengthwise extending opening 4, about which is a rim 5, desirably of the same thickness as the rim 3. Desirably, but not necessarily, the handle 2 is shaped as shown in Figs. 1 and 2 to present a rounded end and inwardly sloping side edges, and the body portion has rounded corners, as shown, at top and bottom.

In the central part of the body 1 there is formed the opening 4, which, in the example here disclosed, is one and seven-eighths inches long. The said opening has quite the appearance of the Figure 8, having the sloping edges 6, 7, 8 and 9 formed at just the proper angle of slope, and against which edges 6 and 8, for example, the sides of the two blades of the scissors or shears to be sharpened are firmly held while being drawn repeatedly back and forth.

The sharpening element of the tool or implement is a removable rounded bar of emery stone 10. The said removable bar 16 is firmly but removably held in the body of the tool or implement, which for that purpose has formed, preferably at the back thereof, two grooves or depressions at just the right angle, so that the removable bar of emery may be placed therein. Such two grooves or depressions are shown at 10 In order to hold the said emery bar 10 in position in said grooves 10 I have provided two short levers or strips 16 pivoted at 16 as shown, and which at their under faces have each a very shallow, very small depression, and the face of the body 1 is provided at the proper points with two very slight, rounded elevations 16 which fit into the said shallow depressions when the levers or strips 10* are in holding position, as shown. The emery bar is held at an angle of sixteen degrees upward slant from left to right viewing Fig. 1. The length of the emery bar that is presented to the blades of the scissors or shears is, in the example shown, five-sixteenths of an inch.

The total length of the opening 4 is desirably one and seven-eighths inches, and the greatest width is ninesixteenths of an inch. In the sharpening process, as shown in Figs. 4 and 5, the slightly opened blades are drawn back and forth while held firmly in contact with the upper side or part and the lower side or part of the emery bar 10.

If desired, there may be an opening 11 near the outer end of the handle, by which the tool or implement may be hung upon a nail or hook in the wall.

Preferably, and as shown in Fig. 2, I provide means to receive and hold a spare emery bar. For this purpose I have represented the back face of the holder or support as provided with a recess 12 here shown as extending lengthwise of the holder or support, but which may be located transversely of said holder or support. In said recess is shown a spare emery bar 13, which is held in position by a short link or lever 14, pivoted at 15. At the end of said lever opposite its pivot there is provided at its under side a very slight depression into which fits a slight elevation on the back face of the said holder or support. If the recess is transversely positioned, the link or lever 14 is vertically positioned when in holding position.

Having thus described a single embodiment of my invention, it is to be understood that although specific terms are employed, they are used in a generic and descriptive sense, and not for purposes of limitation, the scope of the invention being set forth in the following claim.

I claim:

A shears and scissors sharpening implement comprising a plate-like body merging into a co-planar projective handle, the body and handle integrally molded of synthetic plastic material to form a paddle-like unit, the body having centrally therein an elongate two-lobe figure-eight aperture in longitudinal line with the handle,

the respective lobes of the aperture having straight sides inclined inwardly toward the waist of the aperture with the opposite sides of the opposite lobes substantially parallel and offset laterally for simultaneous guiding coaction with the outer faces'of open shear blades inserted in the aperture, the body having at one face transversely aligned bearing recesses at the opposite sides of .and H opening into the aperture waist, a cylindrical abrasive 'member'rotatably received in said recesses, and releasable retainer. means on the body attsaid recessed face for V operatively confining theabrasive member in the recesses,

the latter transversely disposed at a predetermined angle of inclination to the aperture longitudinal axis to present diametrally opposed portions of the abrasive member in rotative sharpening relation to the bevelled cutting edges of inserted shear blades'as guided by said aperture sides.
